Answer:
she will need 27/8 cups so 3 cups and 3/8.
Let me know if you need explanation.
Answer:
You need to satisfy the equation.
I will solve one.
Step-by-step explanation:
x -2 < -5
now add + 2 to both sides to keep its value.
now we end up with x <-3, which means that the value of x should be less than -3 in order to satisfy the equation.
So -5 is an answer, -4 is an answer, but not -3 because it should be less than -3 not equal.
As for number 9 the dash underneath the less than symbol means that it can equal to.
Hope this helps.
Answer:
Verdadero
Step-by-step explanation:
Verdadero, cuando cambias dos fracciones para darles un denominador comun la fraccion entera se sustituye para otra que tiene el mismo valor numerico que la original. Por ejemplo tenemos una fraccion 2/6 en la cual tenemos que cambiarle el denominador a uno comun con otra fraccion que es 18. Entonces sustituyemos la fraccion por la siguente fraccion 6/18. Esta nueva fraccion es equivalente a la original y los dos tienen el mismo valor numerico...
2 / 6 = 0.333
6 / 18 = 0.333
Answer:

It is a perfect square trinomial.
Step-by-step explanation:
The square of a binomial can be solved like this:

We have the expression:

Then, we consider a and b as:

The solution would be:




Answer:
0.1875
Step-by-step explanation:
Let A be the event that class two has been chosen . So the probability of A would be P (A) = 1/2= 0.5
Now class two has 9 girls out of total 24 students . So the probability of chosing the girl would be= P (B=) 9/24= 0.375
So the probability that Classroom #2 was chosen at random, given that a girl was chosen is given by = P(A) . P(B)= 0.5 * 0.375= 0.1875
Another way of finding the probability that Classroom #2 was chosen at random, given that a girl was chosen is by drawing a tree diagram.
P (1/2) Class 1 ------------------------5 boys
-------------------------11 girls (11/16)
P (1/2) Class 2 -------------------------15 boys
-----------------------9 girls P (9/24) Class 2 was chosen (0.5) *9/24
